#Arctic sea ice volume was about 36% below the 1979 level and 20% below the 1979-2024 average in March 2025 + More graphics: zacklabe.com/arctic-sea-i.... Data simulated from PIOMAS.
Line graph time series of daily mean Arctic sea ice volume for each year from 1979 to 2025 using shades of red, white and blue. A seasonal cycle is shown with thicker ice in late winter and thinner ice in late summer. A long-term decreasing trend is also visible. Data is from PIOMAS v2.1.
